JEAN SGHW'EITER, OF HORGEN, SlVITZERLAND.

WEFT-THREAD-SPOOLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 596,794, dated January 4, 1898.

Application filed July 17,1896. Serial No. 599,484. (No modeld Patented in Germany July 1'7, 1894, No. 86,906,- in Switzerland September 22, $94,310. 8,974, and in France October 31, 1894, No. 242,546.

To all 1071/0111 it may concern.-

Be it known that I, JEAN SGHWEITER, a citizen of the Republic of Switzerland, and aresident of Horgen, Switzerland, have invented certain new and useful Improvements in VVeft-Spooling Machines, (for which I have obtained patents in Germany, No. 86,906, dated July 17, 18%; in Switzerland, No. 8,97 4, dated September 22, 1894, and in France, No. 242,546, dated October 31, 1894s,) of which the following is a specification.

In weft-thread-spoolin g machines the spindie on which the thread is wound in so-called conical layers moves relatively to the thread-guide, the threadguide or the spindle being moved up and down in the direction of the axis of the latter, or both are simultaneously moved in opposite directions. Each conical layer which is formed during the upand-down motion either by the rotation of the spindle on its own axis or by the rotation of v the thread-guide around the spindle, abuts at the end of the down winding of the thread against the carrier of the thread-guide and imparts thereby a shifting motion to the thread-carrier in the direction of the upward motion of the spindle, so that each new conical layer appears to be set off for a corresponding length toward the preceding layer and that the spindle is thus gradually covered by these conical layers of thread.

In the present invention the shifting motion, which is produced by the action of the conical layers on the carrier or support of the thread guide, is accomplished through the medium of a rotary ring with the least possible resistance, which ring becomes, at the moment of the shifting action, by the friction, so to say, part of the spindle itself, so that the friction which takes place between the shifting part and the part that is shifted, due to the fact that one of these parts turns on its axis, is thereby removed from the conical layers of thread and taken up by the rotary ring referred to. Hitherto such means were lacking, and in consequence thereof the spooled thread suffered the friction exerted thereon, while, on the other hand, the layers of thread were wound irregularly toward each other on the spindle.

The invention relates, further, to certain improvements in the means for guiding the thread, which consist in the arrangement of of a frictional mechanism for the thread-guiding pulleys, by which the transmission of various speeds to the same may be produced, and, furthermore, in a speed device for this frictional mechanism which is placed in connection with a stop-motion for the spindle of each spool.

In the accompanying drawings, which fully illustrate my improved thread-spoofing machine, Figure 1 represents a side elevation of my improved spooling device. Fig. 2 is a vertical central section of the same, in which the motion-transmitting mechanism and the guides for the spindles are broken away. Fig. 3 is a plan view of Fig. 1. Fig. 4 shows a side elevation of the entire machine with the thread-guiding pulleys, the motion-transmitting mechanism for the latter, and the stopmotions for the same. Fig. l is a detail View of the stop-motion, looking from the rear. Fig. 4 is a detail transverse section of the stop-motion. Fig. 5 is a detail vertical longitudinal section of the upper part of the thread spooling machine with the thread guide rolls and the motion-transmitting rolls drawn on a larger scale. Fig. 6 is aplan view of Fig. 5.

Similar letters of reference indicate corresponding parts.

In regard to the construction of the spool ing device it is assumed that a spindle f has a regular upand-down longitudinal or axial motion, while the thread-guide Z) and its carrierd turn around the spindle and produce thereby the winding up or spooling of the thread. The carrier d is arranged shiftably on two vertical guide-pins c, which are screwed into the friction-disk a, so as to be firmly connected with the same. For the transmission of the shifting action from the conical layers of thread that are formed around the spindle on the carrier d (which shifting action corrospouds to each upward motion of the spindle and the thickness of the conical layers made during the up-aud-down motion) is arranged a rotatable ring h, which surrounds the spindleiand which in the moment of the thrust produced by the layers is retained on the spool by losing the. rotary motion imparted by the in Figs. 2 and 3, antifriction-balls 72/, so that;

only a rolling friction takes place between the parts. This results in the thorough protection of the silk threads and in; an easy. and

effective spooling of the same. The carrier d receives an intermittent or step-by-step shifting motion, so as to gradually assume; different heights, which is assisted bymeans of sllding sleeves 75, through which the guide-' pins 0 are passed, and which sleeves are attached to the carrier (Z and, together with the carrier, retained after each shift by means of a steel spring or catch 2', attached to one of the sleeves hand engaging minute teeth or serrations on one of the guide-pins 0, so that the carrieris thereby retained in its relative position.

The thread guide 6 is formed of an open twisted snail-like body of glass and is supported in a horizontal sleeve Z), the shank b of which is capable of axial adjustment ina socket of the carrier cl, as shown in Fig. 1.

For the purpose of enabling the supplying of very thin and slender threads the threadguiding roll t, by which the thread is guided from the original spool u to the glass rod 1; and to the thread-guide Z) of the spooling device, is operated from the driving-shaft of the machine, as shown in Figs. 4 to 6, in

the following manner: On the driving-shaft islocated a pulley Z, by which the rotary motion of the driving-shaft is transmitted through a belt or cord 8 to a cone-pulley m and from the same, by means of a cross-belt to a cone-pulleyn at the upper party of the machine. The latter is fast on the shaft 0, while the pulleys 19 (shown in Figs. 5 and 6) are placed loosely on the shaft and carried around by the friction which is exerted on the same by the lateral pressure of the helical springs 1', which are interposed between fixed collars q and the hubs of the pulleys 19. From each of the pulleys p rotary motion is transmitted, by means of a belt 3 to the grooved hub of the thread-guiding pulley t.

The latter receives thereby a motion whichis independent of the rotary motion of its spool device and which prod uces the unwinding of the thread from the main spools u, so as-to conduct the thread over the glass rod v to the thread guide of the corresponding spooling device at various degrees of speed according as the cross belt or cord is placed on one or the other steps of the two cone-pulleys m.

Machines of this class are usually provided with ways and means for suitably changing the speed in accordance with the ascending and descending motion of the spool-carriers g-that is to say,as all of the spool-carriers g receive a simultaneous up-and-down vmotion oted at wLis arranged, said lever being con- .nected with each spool device, Fig. 4, 111 a suitable manner, and also being connected with a second lever z which is pivoted at y". The lever x carries the rod a, which engages with the disk a on thehub of the friction-cone a. and when the lever wis moved in upward direction the cone-pulley a is raised and its rotation discontinued.

This operation can take placeat any time according to the desire of the attendant by simply lifting said stop-lever a; but it also takes place automatically in case when the thread breaks. For this latter purpose the rear end of the leverwis sup ported normally in raised position by means of a hook 00 on the lower end of a brealowire 50 which is hinged at m to the frame so as to swing sidewise. There are also arranged L-shaped supporting-arms a which extend parallel with the spool-spindles u and which are mounted to oscillate in theframe through the medium of short shafts or pivots u, journaled in the frame. The oscillating arms w are arranged to extend transversely across .and in juxtaposition to the break-wire a13 whichlat-ter, when the oscillating armsare in raisedposition, as shown in Figs. 4 and l.

is held in'the outwardly-swun g position there shown by reason of the engagement of the hook a? with the lever 12:. The oscillating arms a are held in their upward position by the upward passage of the threads which run from the bobbins. Whenever a thread breaks, the corresponding oscillating arm n drops, thus swinging the break-wire 00 into the posi tion shown in dotted lines in Fig. 45 and thus disengaging its hook m from the lever 00, permitting the rear end of thesaid lever to drop, so that the friction-cone is automatically raised, whereby the motion of the cone-pulley is arrested. Simultaneously the stopping of the corresponding motion transmitting mechansm takes place. For this purpose the lever y is connected at its opposite end with a push-rod e, which, duringthe motion of the machine, is located below the pulley p, but which is shifted in an upward direction in case of the breaking of a thread; so that its upper end is placed in the path of one or the other of two pins .2 on the pulley p, as shown in Figs. Sand 6, so that the further turning of the pulley p is prevented by the contact or the uppermost end of the stop-rod zwith one of the pins 2 on the pulley p, as shown in Fig. 5.

IIO

As soon as the stop-lever a: is lowered and its rear end correspondingly raised the stoprod ,2 is lowered to a corresponding extent out of the path of the pin 2 and offers no re sistance, so that pulley p is taken along with the shaft 0 by the frictional action of the spring r, whereby the normal transmission of the motion from the driving-shaft to the thread-guiding pulley is restored.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a thread-spoofing machine, the combination of a thread-guide carrier 01, with a loose ring it adapted to turn freely in the same and engage the yarn on the bobbin being wound, substantially as set forth.

4. In a thread-spoofing machine, the combination with the thread guiding pulley, loosely-mounted friction-pulley provided with laterally-projecting pins, shafts for both of saidpulleys, means for rotating the frictionpulley, and means for rotating the threadguiding pulley from the friction-pulley, of a stop-motion consisting of the stop-lever w, an intermediate lever y connected with the'stoplever, a stop-rod 2; connected with the intermediate lever y and adapted to engage with the pins of the friction-pulley, the plate or disk a of the spooling device, a contact-rod at carried by the stop-lever wand adapted to contact with said disk 0L0 and the break Wire or rod 18 adapted to act automatically when a thread breaks, substantially as set forth.
